Re-listing the item. Bach 42K Yellow Brass Bell This is a Bach trombone equipped with the now-discontinued K-valve. The instrument was disassembled once by the importer to eliminate assembly stress, and some braces were removed. It has been modified to a K-brace, which is popular these days. As a result, the resonance has increased, and the instrument now produces a rich sound in concert halls and other venues. The slide is non-lacquered on the brass parts only. You can play with a comfortable feel with less resistance due to the stress-free airflow of the K-valve. Since it is a rather old instrument, there is lacquer wear and minor scratches, but the response of the dents and moving parts has been adjusted, so it moves smoothly and beautifully. Replacement parts and removed parts will also be included. Please use them if you want to restore the instrument to its original condition. The case, mouthpiece, etc., are not included. This is a very rare model that is no longer available, so how about taking this opportunity? I will also consider lowering the price, so please comment. #Bach #Back #Trombone #Trombone #42K
